Abstract :
Classical magnet wires used for manufacturing electrical machine and transformer windings are made with polluting processes involving carcinogen solvents and CO2 emissions. Their production also requires significant electric energy. An innovative varnish produced with a more ecological process, without any solvent and no CO2 or NOx emission, has been proposed. The insulation of this copper wire is composed of an UV-polymerized polyester acrylate layer covered by an extruded thermostable resin (polyphenylene sulfide). The present work aims to explore the properties of this new ecofficient coating for magnet wire application. Calorimetric, thermogravimetric and dielectric analyses were performed to study the new coating. Accelerated tests were conducted to highlight the structural and dielectric changes occurring during thermal ageing.
